It's hard enough to get up the courage to start a business, but that's only the beginning. Now you need to decide what business to start, and it's not as simple as doing what seems obvious. For example, a friend of mine learned how to design websites while he was in college. When he decided to start a business, he figured, "I know how to design websites, I guess I'll start a website design business." Others have started certain types of businesses because of a hobby, because they heard it was a good way to make money or because someone else dragged them into it.
